LINOTYPE-MACHINE.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed May 18, 1905. Serial No. 261,088.

To all whom it may concern.-

Be it known that I, CARL L. GROHMANN, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

This invention has reference to the matrixassembling mechanism of machines such as represented in Letters Patent of the United States No. 640,033. In this class of machines there are two matrix-magazines, one overlying the other and both delivering their matrices as they are released one at a time to one and the same assembler, wherein they are assembled in line side by side. The upper magazine delivers matrices directly to an inclined belt, which carries them directly forward to the end of the assembler. The lower magazine delivers matrices to a belt at the rear, from which they descend at one end and are directed forward to the end of the assembler. Owing to the fact that the matrices of the respective magazines approach the assembler in different paths special provision must be made to prevent them from colliding or interfering with one another.

To this end my invention consists in the employment of two guiding blades or springs, one overlying the other, as hereinafter explained.

Referring to the drawings, Figure 1 represents a front elevation of the assembling devices of the Mergenthaler machine with my improvement incorporated therein. Fig. 2 is a cross-section on the line 2 2, Fig. 1.

Referring to the drawings, A represents the upright channels through which the matrices released from the upper magazine descend to I an inclined carrier-belt B, by which they are directed downward endwise over guiding-surfaces C to a position in front of a star-wheel D, by which they are carried laterally one after another into the channeled elevator E against the yielding finger or resistant F. The belt B, assembler E, and intermediate parts are all in the same vertical plane, so that the matrices from the upper magazine pass forward in a direct line to the assembler, as in the ordinary linotype-machine, such as represented in United States Letters Patent No. 436,532. The matrices from the rear magazine are guided forward and downward through a chute b, terminating above the supportingsurfaces C, in order to direct the matrices of the lower magazine into the same path as that followed by the matrices of the upper magazine on approaching the star-wheel and assembler. The form and arrangement of this chute and the parts for delivering matrices thereto are fully explained in the application of John R.'Rogers for United States patent, Serial No. 243,033, filed January 28, 1905.

The machine'contains, as usual, a series of expansible wedge-spacers, which are delivered from their magazine downward to the receiving end of the assembler through the upright guide or channel G, as usual in linotype-ma chines.

In order to prevent the interference of the space-bands and matrices, a spring-finger H is located as shown in the drawings, its lower and free end terminating above the assembler and at such distance from the supporting-surface O as to permit the free passage thereunder of the thickest matrices employed. This finger closely resembles that heretofore employed in all linotype-machines.

In carrying my invention into effect I introduce between the spring-finger H and the matrix-supporting surface C an intermediate finger I, fixed at its upper end to the frame at a considerable distance above the carrierbelt B and extending thence downward to a point one inch, more or less, above the starwheel D. The matrices from the upper magazine pass beneath the finger I, while those from the lower magazine pass thereover. The finger serves to prevent the matrices issuing from the chute b and those descending on the surface C from colliding or interfering with one another. In other words, they are compelled to pursue different paths until they have passed the lower end of the finger I and are in position, or practically so, to be acted upon by the star-wheel and enter the assembler. The intermediate finger is of special importance when thick matrices for large type-faces are used in one magazine and thin matrices for smaller type-faces used in the other. Before the employment of my finger I it was found necessary to change the shape or position of the finger H when a material change was made in the size of the matrices employed.

The essence of the invention lies in the employment of the intermediate finger or spring to separate the matrices of the upper and lower magazines until they have arrived at or near the assembling-point.

Having described my invention, what I claim is 1. In a linotype-machine of the class described, an assembler, means for directing matrices from the upper magazine thereto, means for delivering matrices from the lower magazine thereto, and a finger or guide to separate the matrices from the respective magazines until they arrive at or near the assembling-point.

2. In a linotype-maehine, the combination of the assembler, a matrix-guiding surface 0, a belt B, delivering matrices thereto, a chute
